stateless.js - simpler pushstate

Lightweight cross-browser context persistence library à la pushState, via changing the hash fragment. Mainly meant for freeloading serverless web applications which need to store some state in the URL. Also comes with a super simple API. Prevents repeated processing - if the same hash is pushed twice consecutively it will not be processed twice. This is useful for example when you have some expensive calculations. Ability to mark hashes as processed - they will still be pushed to the browser's history stack but they will not be processed by any Stateless handlers. Asynchronous handlers via hooking into hashchange.
